High dietary phosphorus and renal indicators in cats
Nine cats developed glucosuria and microalbuminuria under high-phosphorus feeding; creatinine clearance decreased.
Review scope
Abstract-based review. Full methods, complete statistical results and product equivalence have not been appraised. This is research context, not an individual feeding or treatment recommendation.
Study question and design
13 healthy adult cats. A high-phosphorus diet providing approximately five times maintenance requirements versus balanced control feeding for 29 days.
Main findings
Nine cats developed glucosuria and microalbuminuria under high-phosphorus feeding; creatinine clearance decreased.
Limitations and applicability
The tested formulation does not establish equal risk for every phosphorus source or a universal safe threshold.
Ingredients investigated
Multi-ingredient formulations
Phosphorus
Multi ingredient · cat. 13 healthy adult cats.
Tested form: High-phosphorus experimental diet; exact phosphate salts not established in the reviewed abstract. Dose: Approximately five times the maintenance requirement (Dietary phosphorus relative to maintenance requirement; oral feeding. Exact concentration not established in the reviewed abstract). Duration: 29 days. Comparator: Balanced control diet.
Measured finding: Nine of 13 cats developed glucosuria and microalbuminuria; creatinine clearance decreased during the high-phosphorus feeding period.
Limitations: Small healthy-cat experiment and short duration. Phosphate source and calcium-to-phosphorus ratio are not established in the abstract; these findings cannot be applied using the ingredient name alone.
This ingredient was part of a combined formulation; the study does not isolate its contribution.
Evidence.pet interpretation
Apply this result only within its species, preparation and study conditions. An ingredient listing alone does not establish that a commercial product reproduces the tested intervention.
Funding and conflicts
The authors declared no conflicts of interest. Funding was not established from the reviewed abstract.
Ingredient references
These are research references. The tested form, dose and formulation must be matched before using a result to support a product claim.
